Ans 4:
Class : Class 7
The answer is absolutely wrong. A perfect number in which the sum of it's factors is equal to the number.
Ans 6:
Class : Class 6
OHHHH I GET IT
6 is a perfect number because 1,2, and 3 (its factors other than itself) Add up to it. But the people that made the test included 6 as well, which was wrong but atleast we know why they did that now
Basically the way your supposed to do it is to add all the factors of a number other than itself, but the people that made the test added itself, which is why its double.
1+2+3=6
1+2+3+6 = 12 = double of 6
Ans 9:
Class : Class 9
it is wrong.a perfect number is the one whose factors,when added ,gives the same numberhence,it is wrong
Ans 11:
Class : Class 6
its wrong
a perfect number is when all the factors add up to the number itself, not double the number.
Ans 13:
Class : Class 6
I said statement 2 is false but it came wrong and when I referred my book and googled it it showed :a perfect number is a number that is equal to the sum of its proper divisors. for eg. 6 3 2 1=6 hence 6 is a perfect number
